Idukki is a South Indian district in the state of Kerala, which is highly susceptible to landslides. This hilly area which is a hub of a wide variety of flora and fauna, has been suffering from slope stability issues due to heavy rainfall. A well-established landslide early warning system for the region is the need of the hour, considering the recent landslide disasters in 2018 and 2019. This study is an attempt to define a regional scale rainfall threshold for landslide occurrence in Idukki district, as the first step of establishing a landslide early warning system. Using the rainfall and landslide database from 2010 to 2018, an intensity-duration threshold was derived as I = 0.9D-0.16 for the Idukki district. The effect of antecedent rainfall conditions in triggering landslide events was explored in detail using cumulative rainfalls of 3 days, 10 days, 20 days, 30 days, and 40 days prior to failure. As the number of days prior to landslide increases, the distribution of landslide events shifts towards antecedent rainfall conditions. The biasness increased from 72.12% to 99.56% when the number of days was increased from 3 to 40. The derived equations can be used along with a rainfall forecasting system for landslide early warning in the study region.

AbstractThe Idukki Reservoir at an altitude of 748 m covering an area of 53 km2 is surrounded by tropical forests in the Western Ghats in the southwestern Indian state of Kerala. We used the small autonomous underwater vehicle (AUV) Maya with onboard sensors of dissolved oxygen, chlorophyll, turbidity, temperature, and depth to monitor the water quality environment of the Idukki Reservoir in May 2006. The use of AUVs in confined spaces like small lakes and reservoirs is new and uncommon, requiring extra safety to be implemented. As this is a prototype AUV, we shall describe in brief key aspects of the vehicle attributes, namely, its novel mechanical design, the autopilots that control the heading and cruising depth, and the safety and endurance of the platform. The data acquired by Maya revealed an acute oxygen deficiency at 21 m, a mid-water low turbidity layer between 10 m and 15 m, and a prominent chlorophyll maximum in the thermocline region of Idukki waters at 6 m. These experiments were repeated a year later in May 2007 and were in unambiguous agreement with the 2006 findings of hypoxia. These are the first observations of hypoxic processes using a small AUV in any Indian lake. The relevance of these results in freshwater systems shows similarities to hypoxia in saline coastal waters of the west coast of India and is discussed briefly.

<p>The effect of mobile tower radiation on child health in an ecologically sensitive area of Western Ghats in Idukki, Kerala is studied. In this paper, we have attempted to discover whether any relation exists between the RF exposure and the health of children under 15 years old. At some point of path of this work, twenty common diseases were considered. From our analysis, it has been discovered that five of them are very much related to RF exposure. Furthermore, the age group between ten to fifteen years is more vulnerable to mobile tower radiation, and boys are observed to be more affected than girls. In the region under study, exposure levels were well below the ICNIRP recommendations and the current Indian standards. However, still it is inadequate to safeguard children. So it is recommended to modify the current Indian standard of RF exposure.</p>

Presently, in India, avocado cultivation is limited and scattered in southern and north eastern region of India. Many avocado genotypes are available in Kerala, which vary widely in terms of biochemical and morphological attributes. In the present study, 27 accessions (Acc.) were collected from different parts of Kerala, including high-altitude areas and plains. Wide variability in biochemical and morphological traits was observed among accessions collected from different locations. Acc. 11 had the highest vitamin C and Acc. 15 had highest protein content. The highest fat content was recorded in Acc. 7, while the highest oleic acid was recorded in Acc. 10. Acc. 25 reported the highest flavonoid and calcium content. Genotypes collected from Wayanad recorded comparatively higher values for vitamin C, phenols, potassium and crude fibre content. Protein, total fat and calcium contents were comparatively higher in genotypes collected from Idukki. Accessions 7, 10, 11, 12, 14, 15 and 25 could be selected for future conservation, popularization and commercial cultivation based on their biochemical and morphological quality attributes.

On the windward side of Western Ghats, the frequency of landslides has significantly increased in recent years. Kerala had catastrophic landslides and floods in 2018, 2019, 2020, and 2021, resulting in loss of lives and property. On October 2021, a cloudburst occurred in middle Kerala, causing multiple devastating landslides in districts of Kottayam and Idukki. The study focused on how the topographic, physical, geological, and anthropogenic factors in the windward slope of the Western Ghats influence the occurrence of landslides. The landslide susceptibility was analyzed using the frequency ratio method on the basis of recently occurred landslide locations in the Manimala river basin, with special reference to Kootikal. The impact of each factor was analyzed against the GPS coordinates of landslide locations to estimate the frequency ratio value. The findings revealed that the torrential rainfall experienced in Kerala and the anthropogenic activities, especially the watershed management work performed in the area, significantly increased landslide susceptibility of the basin. About 5% of Manimala river basin is highly susceptible to landslides, and this area comes under the Kootikal sub-basin. The study recommends a rigorous geophysical assessment on the influence of watershed management operations on a landslide and an EIA of roads in the Kootickal region.

The genus Vigna has several crop species that could be used to feasibly address nutritional security challenges in the subtropical and tropical regions of the world, particularly in climate-changing scenarios. Wild taxa of Vigna are a source of economically important traits and need to be studied. Out of the 34 wild Vigna species reported in India, 928 indigenous accessions belonging to 19 wild Vigna are conserved in India’s National Genebank (INGB) housed at the National Bureau of Plant Genetic Resources, New Delhi. Geospatial mapping has identified diversity-rich areas and the Western Ghats region exhibits the highest Shannon diversity values (H = 1.65–3.0). Using the complementarity procedure, six diversity hotspots were identified for the 34 wild Vigna, and these require utmost priority for exploration and germplasm collection. Due to the meagre amount of information available for wild Vigna, the BioClim model was used to successfully predict the Idukki district of Kerala as a suitable site for germplasm-collecting expeditions. Coastal areas identified as rich in twelve wild taxa, V. bourneae, V. dalzelliana, V. marina, V. sublobata, V. subramaniana, V. vexillata, V. stipulacea, V. trilobata, and V. trinervia, require immediate attention to protect hotspots as well as to collect accessions from these areas for ex situ conservation. A hotspot in the protected forest of Anshi National Park and Bhagwan Mahavira Wildlife Sanctuary was identified as an ideal spot for possible in situ conservation of V. konkanensis, V silvestris, and V. sublobata. The 15 wild Vigna species do not have representation in the INGB, and 11 Vigna species have been identified as endemic species to India. Priority needs to be given to these species for focussed exploration and germplasm collection. This paper discusses the future focus on explorations to be carried out for the collection of the germplasm of wild Vigna species.

Kerala, the spice bowl of India is popular for tropical spice crops like pepper, cardamom,nutmeg etc. Garlic, an important foreign exchange earner of India is produced mostly inthe states like Madhya Pradesh, Rajasthan and Gujarat. In Kerala it is grown commerciallyin two unique rain shadow pockets, Kanthalloor and Vattavada regions of Devikulamblock of Idukki district. Although garlic is grown in the high ranges of Kerala, itscultivation in plains are not evaluated so far. Generally cool season crops performs wellinplains when grown during October – March. Hence the present study was conducted toevaluate the performance of two genotypes Singapore and Mettupalayam in the plains.The two garlic genotypes were grown as pot culture during October – February in the year2016-2017, in the plains of Thrissur district, the central part of Kerala. Among the twotypes Mettupalayam was found to be recorded higher Bulb weight (14.53g) and number ofcloves per bulb (4.2), but it was less compared to that grown in high ranges (17.19g and11.9 respectively). Hence the study revealed the possibilities of garlic cultivation in theplains of Thrissur district of Kerala with some refinements in agro techniques.

When weathering causes a rock to crumble and decay, the shabby material, wet with rain water, May float due to gravity.The phrase "land slippery" denotes to a rapid downhill slide movement of rock rubble. They may grow on any piece of ground if the soil, moisture, and slope conditions are rig ht. Landslides are an important part of the earth science activities on the surface of the planet and for happening of those when he condition of the soil is good and moisture contain is maintained and angle of slope must be maintained .Due to landslide failure of slopes, failure of earth surface and flow of mud, flow of boulders, can happened .the main factor of the movement is due to either earthquake which shakes the earth surface and movement of mass can happened and it could occur due to when deep excavation could have been made for the construction of various structures like buildings and it could happen because when the precipitation is heavy and its happening for long duration like what happened in Idukki in 2019. Water is not only the factor for landslide or movement of slope but weathering of rocks plays a predominant role in landslide .shear strength of the rocks is reduced due to weathering. Many researchers have found that the main reason is weight of building and their slope which act downwards due to gravity is one of the main reason for movement .to prevent the movement of mass some resisting force is applied which is in the opposite direction of friction angle and when the earthquake is for long duration the forces is automatically reduced for different kind of landslide the movement speed will be different its depend on the weight of the mass movement.
